Workspace Method ySimpleSpectrometer


Converts iy to y assuming a fixed frequency resolution.

This is a short-cut, avoiding yCalc, that can be used to convert
monochromatic pencil beam data to spectra with a fixed resolution.

The method mimics a spectrometer with rectangular response
functions, all having the same width (*df*). The position of
the first spectrometer channel is set to f_grid[0]+df/2.
The centre frequency of channels are returned as y_f.

Auxiliary variables and jacobians are not handled.
